What It DoesThe YD‑4 combines pressure measurement, digital display, analog output, and alarm
control in one explosion‑proof device. No need for separate gauges,
transmitters, or switches.
Key Features (Simple)Ex d II C T6 Gb explosion‑proof – safe for Zone 1 & Zone 2 hazardous areas All‑in‑one design – measure, display, transmit, and control Field adjustable – change range and alarm points on‑site without factory tools Multiple outputs – 4‑20mA, 0‑5V, 0‑10V, RS485 (Modbus), and HART (optional) 2‑channel alarm control (customizable for more points) Rugged housing – cast aluminum, dust/water resistant Clear 4‑digit LED display – easy to read at a glance
Basic Specifications (No Table)Pressure range: –0.1 ~ 0 ~ 260 MPa (selectable within range) Accuracy: 0.2% FS ±1 Power supply: AC85~260V or DC24V Power consumption: less than 3W Operating temperature: 0 ~ +70°C Contact capacity: AC220V 3A Sampling rate: 3 times per second
Why Keep It Simple?One device replaces three – saves cost and installation time Easy to set – use buttons on the front panel; no computer needed Works in tough places – shock, vibration, and corrosion resistant Certified safe – designed for explosive gas or dust environments
Typical ApplicationsPetrochemical plants and gas pipelines Municipal water and gas distribution Boiler rooms and HVAC systems Hydraulic machinery and industrial equipment
